Abstract

The hydrostatic axial piston machine (1) has a pivoting cradle (40) that is pivotally arranged in the housing. The pivot angle of the pivoting cradle is adjusted by an adjusting device (44). The adjusting device is provided with a cylinder-piston unit (45) and a spring (52). The axial section of the cylinder piston unit is encompassed with the spring.
